Big Tuna Bonanza (Mini Review)
BGaming reels in the action with Big Tuna Bonanza, a fishing-themed slot played on a 5×4 grid with 10 paylines. It runs on medium volatility, boasts an above-average RTP of 97.20%, and offers a solid hit frequency of around 1 in 3.2 spins. Betting ranges from €0.10 to €50, with a maximum win potential of 5,000x the stake.
The centerpiece is a Free Spins bonus triggered by 3 or more Bonus symbols, awarding up to 20 spins. Wilds collect Prize symbols during the round, while every 4th Wild retriggers the feature with 10 extra spins and an upgraded multiplier—progressing from x2 to x3, and finally x10. In the base game, Prize symbols can also pay directly, though in Free Spins they must be collected by a Wild. Players can buy straight into the bonus, unless using the Chance x2 mode, which instead increases the odds of triggering it naturally.
While the setup is familiar, echoing the massively popular Big Bass Bonanza series, Big Tuna Bonanza still shines with its bright visuals, smooth flow, and reliable math model. It’s not the most original catch, but it delivers the kind of “fish & collect” fun fans of the genre keep coming back for.
